WINDMILL ATTACHMENT.

Application filed October 17, 1922. Serial No. 595,141.

To aZZwhom it may concern:

Be it known that I, JOSEPH P. BERGER, a citizen of the United States,and a resident of Uvalde, in the county of Uvalde and State of Texas,have invented certain new and useful Improvements in WVindmillAttachments, of which the following is a specification.

My invention relates generally to attachmentsforwindmills, and itconsists in the combinations, constructions and arrangements hereindescribed and claimed.

More specifically, my invention is an at tachment for windmills of thetype of construction in which a so-called cut-ofi chain or cable isprovided to automatically cut off or discontinue the driving connectionbetween the wind wheel and the plunger of a pump with which the windmillis associated when a sudden change takes place in the direction of thewind.

In windmills of the type of construction described the wind wheel andthe rudder are ordinarily supported, so that the rudder is mounted uponthe said supporting means for independent rotation about a verticalaxis, being also connected with the said supporting means through theagency of the socalled cut-off chain or cable which is attached at itsends to the rudder at spaced apart points and is trained about aplurality of spaced guide pulleys carried by the said supporting means.In strong winds, the cutoff chain or cable frequently disengages theguide pulleys, thereby precluding the functioning of the cut-off chainto control the operation of the pump plunger in the manner described.

An object of the invention is to provide an attachment embodying meansfor preventing the cut-off chain or cable from disengaging the guidepulleys without interfering in any way with the functioning of thecut-off chain and pulleys in an ordinary manner and in accomplishing theresult for which provided.

A further object of my invention is to provide an attachment of thecharacter described which is relatively simple in con struction and isadapted to be operatively applied to a windmill of the class referred towithout any change in the ordinary construction of the latter beingrequired.

Other objects and advantages will be apparent from the followingdescription, considered in conjunction with the accompanying drawings,in which:

Figure 1 is a fragmentary perspective view, showing a windmill equippedwith my invention, only such parts of the windmill being illustrated asare deemed essential to an understanding of the invention, and of theapplication thereof,

Figure 2 is a relatively enlargedperspective view, showing one of a pairof retaining guides included in the embodiment of the inventionillustrated in Figure 1,'

Figure 3 is a view similar to Figure 2, showing the other of the pair ofretaining guides,

Figure 4 is a perspective view showing a third guiding and retainingelement included in the device, and

Figure 5 is a perspective view showing in detached position a carryingframe included in the windmill for supporting pulleys with which theaforesaid pair of guiding and retaining elements is associated.

Referring now to the drawings and particularly to Figure 1 thereof, Ishow a vertically disposed supporting column 1 supported by verticallyspaced horizontal sup porting plates 2 and 3 respectively, the saidhorizontal supporting plates being carried by a plurality of upstandinglegs 1. The supporting column 1 rests at its lower end in a socket 5upon the horizontal supporting plate 3.

A collar 7 is secured upon the column 1 at the upper end of the latter,and is provided with oppositely extending bracket arms 8 and 9respectively. The turn table 9 of a rudder designated generally at-lO ispivotally supported at the outer end of the bracket arm 8 for rotationabout a vertical axis parallel with, but spaced from the vertical axisof thecolumn 1. The rudder 10 also includes a vane 11 which is securedat its one end to the turn table 9 and is disposed. substantially in avertical plane.

A windwheel 12 is rotatably supported at the outer end of the bracketarm 9 for rotation about a horizontal axis.

A frame 13 havingthe form of a bar provided with pairs of spacedupstanding arms or forks 14e14c at opposite ends thereof, as best seenin Figure 3, is supported upon the collar 7 and carries a pair ofpulleys 15 and 16 respectively, each of which is rotatably supported innotches le -14? Figure 1 at 21), in opposite sides in the upper ends ofthe upstanding arms or forks 141-1 1 at an end ofthe frame 13. Thepulleys and 16 are mounted for rotation about horizontal axes. A thirdpulley 17 rotatably supported upon a horizontal shaft or stud 18projecting laterally from the column 1 adjacent to the lower end of thelatter. A cut-off chain or cable 19 is attached at its opposite endstothe turn table 9 at opposite sides of the latter and extends in aperipheral groove 20 in the turn table toward the upper end of thecolumn 1, be ing trained about the pulleys 15 and 16 and extendingdownwardly in the column and through apertures, (one of which is shownin of the latter into engagement with the pulley 17. One of thesubstantially vertically extending portions of the chain or cable isflexibly connected as at .21 with a lug 21 extending through theaperture 21 from a traveller 21 which has a pair of outwardly extendinglugs or radial extensions 21 having notches "21 in sliding engagementwith vertical guides 21 The traveller 21 carries depending rods 21 forconnecting it with a suitable arrangement (not shown) for cutting offthe driving connection between the windwheel and a pump plunger upon adetermined vertical movement of the traveller. The parts described sofar are ordinary in construction and form no part of my invention exceptin so far as they cooperate with the parts which will now be described.

My invention provides a guiding and retaining element 22 associated withthe pulley 16, a second guiding and retaining element 23 associated withthe pulley 15 and a third guiding and retaining element 24: associatedvith the pulley 17 whereby the cut-elf chain or cable 19 will beeffectually held against disengaging the pulleys without anyinterference with the rotation of the pulleys, or with the movement ofthe cut-off chain or cable while in engagement with the pulleys. Theguiding and retaining elements or memhere 22, 23 are identical inconstruction in essential respects, being adapted for positioning atopposite ends of the frame 13 as will presently appear, and thereforediflien ing from each other in construction only in that one is a righthand member, while the other is a left hand member. It is thereforethought that the illustration of the guiding and retaining members 22and 23 and the following detailed description of the former will suflicealso to disclose the construction of the guiding and retaining member23. Reference characters denoting portions of the member 22 havetherefore been primed to designate corresponding portions of the member23.

The element or member 22 comprises a plate portion 25 adapted to beinserted at the one end of the frame 13 between the latter and a flange26 which extends laterally of the upper edge of the collar 7 and withwhich the bracket arm 8 may be integral. A pair of upstanding ears 27-27 at the inner end of the flat plate portion 25 are adaptedto straddlethe frame 13 and. are provided with turn table 9. The tubular guide 30is 10- I1 cated at a level lower than that of the highest point on theperiphery of the pulley 16. The portion ofthe cut-off chain or cable 19extending from one side of the turn table over the pulley 16 will thusbe held in engagement with the pulley 16 when threaded through the guide30. l

The plate 25 has an extension 31' depending from the side thereofopposite that provided with the extension 29. The extension 31 isprovided with a vertical tublar guide 32 at its lower end. The extension31 is preferably arcuate in cross sectional contour so as to conformsubstantially to the contour of the inner wall of the collar 7, and tothus permit of the positioning of the guide 32 close to the inner wallof the collar and out of the way of any part of the windmill which maybe extended through the collar and through the column 1.

The guiding and retaining member 2 1 comprises a flat body which issubstantially triangular in outline and is arranged in invertedposition. The body 33 is provided with an opening 3 1 therethroughadjacent to its lower end and this opening is adapted to the stud orshaft supporting the pulley 17. An attaching portion 35 at the upper endof the body 33 is provided with a plurality of openings 36 through whichbolts 37 or the like may be projected into engagement with the column 1.The body 33 willthus be held in such relation to the pulley 17 that apair of vertical tubular guides 3838 provided at opposite sides of thebody 33 in positions laterally offset therefrom aresupported with theiraxes lying in a vertical plane extendingthrough the pulley 17intermediate of the sides of the latter.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The

a and retaining members 22-23 and secured in the positions described.

Hill

The cut-oil chain or cable 19 is secured at one end to the rudder turntable 9 at one side of the latter and forwardly of the transverse medianline of the latter. The cut oil chain or cable is then passed throughthe horizontal guide 30 of the guiding and retaining member 523, thenover the pulley 15, downwardly through the vertical guide 32 of theguiding and retaining member 23, then connected with the lug 21 of thetraveller 21", then extended downwardlythrough one of the guides 38,then about the pulley 17 and upwardly through the other guide 38,through the vertical guide 32 of the guiding and retaining member 22,over the pulley 16, through the horizontal guide 30 of the guiding andretaining member 22, and is then attached at its end to the turn table 9at a point directly opposite that at which the first named end isfastened to the turn table. When the rudder 10 turns on its axisindependently of the column 1, as when a change in the direction of thewind takes place, the cut-oif chain or cable is permitted to movelongitudinally in respect to the several guiding and retaining membersand pulleys, but is prevented from disengaging the pulleys. lhe cut-offchain or cable is thus maintained continuously in position to performthe function for which provided, that is, to efiect such connection 7between the rudder and the means for rotatably supporting both the windwheel and the rudder, as will result in automatic con trol of the meansfor cutting off driving force from the windwheel to a pump plunger.

Obviously, my invention is susceptible of embodiment in forms other thanthat illustrated herein, and I therefore consider as my own allmodifications and adaptations of the form of the device herein disclosedwhich fairly fall within the scope of the appended claims. I

I claim:
